Abstract: A locking mechanism as shown in the figure for the contouring head assembly (108 ) of a belt grinding machine that employs multiple, parallel, abrasive grinding belts (62, 64; 66, 68; etc.) and back-up s hoes (254) for pressing the belts against the surfaces on a workpiece to be ground. The locking mechanism secures the contouri ng head assembly (108) to the bed of the grinding machine. The locking mechanism includes a protrusion, such as a ball (256) that is carried by the contouring head assembly (108) and a pivotable arm (156) is secured to a shaft (151) that is driven by a rotary actuator, that is powered by a hydraulic motor (150). The socket (266) engages the protrusion (256) to securely support one sid e of the contouring feed assembly.

Abstract: A cardiac pacemaker improves battery longevity by automatically providing optimized threshold amplitude and pulse width values. During capture verification and threshold searching, the pacemaker delivers a pacing pulse and a rapid, maximum amplitude backup pulse in case the pacing pulse fails to capture a patient's heart. Unlike the prior art, the backup pulse is delivered before a predefined Vulnerable Period (during which time pacing might lead to re-entrant tachycardia or fibrillation.) This results in threshold searching which is quick, accurate and with smaller rate drops during loss of capture.  In another aspect of the present invention, a diagnostic strength-duration curve is approximated by first setting the pulse width to a maximum value and determining the amplitude threshold (rheobase), and then by doubling the amplitude and determining the pulse width threshold (chronaxie).
